There's just over a month to go until Season 3 of 'Stranger Things' hits Netflix, and now a new teaser has been released.

Titled 'Summer in Hawkins', it doesn't give us a whole lot of new information - and no glimpse of the Upside-Down, either. However, it does tell us that bully Billy Hawkins, Max's big brother, is returning for Season 3, as it shows him on lifeguard duty at the town pool.

A previous teaser had suggested that the mall would be pivotal in this season, but it seems that pool may also have a role to play.

Could Billy also have a bigger role to play this season?

Netflix have also released some new illustrated posters featuring the main characters:

One summer can change everything? Well, we only have until July 4th to wait and see what that really means.
